[Legacy] H3 Continuum Load Session

H3 Continuum Load Session is the flip side of Save Session: it loads an explicitly numbered V2 session back from disk so you can resume or reroll a continuation run without regenerating everything. Feed it a prefix and slot - same values you used when saving - and it hands you back the H3_CONTINUUM_SESSION plus a path STRING for the file location.

That session object then plugs into a H3 Continuum Sampler V2's optional session input. Combined with the sampler's reroll_from_chunk, this is how V2-era users did surgical fixes: load the session, tell the sampler to regenerate from chunk 4, and chunks 1–3 get reused from the saved acceptances instead of being sampled again. The slot range goes up to 9999, so you can keep multiple runs of the same prefix around and switch between them by changing one number.

Install

cd ComfyUI/custom_nodes
git clone https://github.com/ukr8b3g-cmyk/ComfyUI-H3-Continuum.git

or via ComfyUI Manager ("H3 Continuum"), then restart. No extra pip packages; needs a MiniMax H3 ComfyUI environment (weights not bundled) and ComfyUI v0.32.0+.

Two practical notes. First, a loaded session only helps if it's compatible - the V2 sampler's reroll logic reuses "every matching accepted chunk," so if you changed resolution, prompt format, or continuity since the save, the old chunks won't match and you'll regenerate anyway. Second, if you're starting fresh, the modern samplers (V3.2.4+) make this node unnecessary: run_storage = Save + Auto Resume auto-detects and resumes compatible saved runs with zero node wiring. Load Session is the manual, explicit version of that convenience - and it's still the right tool when you're deliberately juggling multiple saved runs in a V2 workflow.
